LUBRICATOR.

Specification of Letters Patent.

Y Application filed December 27, 1920. Serial No. 433,358.

To all who/m, t may concern:

Be it Vknown that I, WILFRED GLUCOLES, a citizen ofl the United States, residin at Madison, in the county of Dane andV tate of Wisconsin, have. invented certain new and useful Improvements in Lubricators, of which the following is a specification.V

'This invention pertains to lubricators and more directly tothe force feed type wherein a pump or series of pumps is employed to force the lubricant.

The invention has to do more particularly with theactuating means employed to operate the pump shaft and is designed Vespecially for use in lubricators wherein 'the pump (or pumps) and the allied parts are inclosed within a reservoir or casing.

The structure is shown Vin the annexed drawings, wherein Figure 1 1s a vertical sectional'vi'ewof a single lubricator unit or pump and the actuating mechanism, taken on the line I--I of ig. 2 a'transverse vertical section taken on the line IIhII of Fig. 1;

3 a detail sectionalview on the line III- II of Fig. 2; and

Fig. 4 a perspective view of the actuating shaft, link or pitman, and the pawl carryinarm.

he main object of the invention is to provide a simple and effective Vmechanism for actuating the pump, the main driving shaft yof which alone extends through the wall of the reservoir or casing. A further object is to so construct and position the parts that they may be readily withdrawny from the reservoir upon the removal ofthe cover, the various elements bein connected to and sustained by the cover. n the drawings, v1 denotesthe reservoir and 2 the removable cover therefor. The oil forcing element (or elements-only one being illustrated) takes the form of a pump comprisin a cylinder 3, with a piston 4 working t erein, the Outlet or discharge pipeV being indicated by 5 and the intake pipe by 6, the latter being shown as broken away but normall extending well down into thev reservoir. uitable means,'designated generally by 7, may be employed to control the amount of oil ejected at each stroke but such forms no part of my invention. Pis-l Patented N0v.15,1921. y

ton 4 has connected thereto a yoke 8 which 'I in turn is connected to an eccentric strap'9 mounted upon an eccentric 10 formed upon a sleeve or collar 11. Said sleeve is'carried on a shaft 12 which extends therethrough and through a similar sleeve 13 to the vleft` and through other sleeves to the right if more than one pump element be present. Shaft 12 is free of any connection with the casing but forms an alining member for the various sleeves `and a support for the hubV 14 of a ratchet wheel 15. Hub 14 is interconnected with sleeve 11` through the medium of lugsl 16 and slots 17, and the sleeve is similarly connected to the' other like elements to the right where more than one pump element is present. Sleeve 13 (and the corresponding element at the right of the structure-not shown) is interconnected with a stub shaft 18 mounted ina suitable lbearing 19 secured in the side wall of the casing. y

Secured to the under side ofthe cover 2 by machine screws 2O is a block or casting 21, said block forming the support for a shaft 22, the shaft carrying at its inner end a wrist pin or eccentric stud 23. A shaft 24 having a head 25 which is in driving engagement with shaft 22, is mounted in a bearing 26 fixed in the side wall of the casing or reservoir, motion being imparted to said shaft 24 and consequently to shaft 22 through a rocker arm 27. A pulley may be substituted for thev arm when continuous rotary motion is desired rather, than an oscillating one. A hanger 28 extends down-V wardly from the under side of the cover, said hanger at its lower end being formed with a hub or bearing 29 Vthrough which the sleeve 13 extends. The hangeris also pro-Y vided with a lateral extension (see Fig. 2) havingan opening therein into which extends a flange or reduced portion 30 formed on the casting 21. The hanger thus assists in holding the block or casting 21 in position and the block likewise assists in maintaining the hanger in proper position with the other parts of the apparatus. The hanger 28 is provided with an outwardly extending Vportion' 31 formed by pressing the v,bcdy thereof outwardly and upon. said out# f vman 37, the pitman being ward extension there is secured a stud 32 which forms the pivot or fulcrum for a rocking frame 33 having formed therewith a locking pawl 34. A spring 35 coiled about the stud 32 having one end bearing upon the fra-me and the other upon an outwardly extending lug 36, tends to hold the' pawl in locking relation with the teeth of the ratchet wheel 15. y

Journaled upon the eccentric 23 is a pitheld in place thereon by apin 38.` The wer end of the pitman passes between the ends of a bifurcated lever 39 and a pin 40 passes through said pitman and the lever, connecting the same together. The inner end of the lever 39 is provided with a hub 41 which encircles the sleeve 13 which forms the bearing for the lever. The pin 40, as will best be seen upon reference to Fig. 3, is connected to the lever 39 and extends outwardly beyond the same past the ratchet wheel 15. Mounted upon said extending portion is a frame 42, similar to the frame 33, and having formed therewith a pawl 43 which likewise coacts with the ratchet wheel 15. A spring 44 taking'against the frame and a lug 45 extending outwardly from the lever 39, serve to force the pawl into contact with the teeth of vthe ratchet wheel.

The Yoperation of the structure is as follows: l

lVhen the rocker arm, as 27, is employed, an oscillating movement is imparted to the shaft. 22, and, as a consequence, the lever 39 is rocked back and forth through the action `Thus the pump is given a periodic impulse and the oil forced to the point to be lubricated. lUpon'the down stroke of the piston under the next actuation of the parts, oil will be drawn into the cylinder through the intake pipe 6. When for any reason it is desired to have access to the parts, all that ,is necessary to dois to remove the cover fasteners and bring the operative parts to that position where the shaft 22 will be free to slideupwardly away from the hub 25 and the sleeve 13 away from the head of the stub shaft 18. The cover and all of the attached parts, including the pump and the actuating mechanism therefor, may then be drawn upwardly from within the Areservoir and as Yreadily replaced when desired. By having the operating shaft 24A located in the bearing at the upper part `of the reservoir the chance of. leakage is minimized. `Where the Shfl extends through the lower portionof the casing it is submerged in oil at all times except when the supply runs extremely low and leakage is liable to occur notwithstanding the employment of packing glands and the like. p'
